Can battery-supercapacitor storage be integrated into a grid-connected PV system?

Regarding the supercapacitor equivalent circuit, the two branches model is examined. For the lithium-ion battery storage model, a dual polarization model with two parallel RC networks is studied. The next step is to integrate the hybrid battery-supercapacitor storage into a grid-connected PV system.

What is a micro-grid?

The below illustrated micro-grid is small scale which is divided into three important parts: Renewable energy sources, load and grid. Two renewable energy sources are included; PV array and a simplified model of a wind turbine. The load is the energy required for two small industries: Fodder production and hydrogel.

Does microgrid voltage regulation work?

The performance of the designed controller for microgrid voltage regulation was evaluated in various circumstances. The controller stabilized the DC microgrid in contradiction of unfavorable effects from the source of PV production and different load types. It might use the built-in fast dynamics of the SC to quickly absorb microgrid transients.

Principles and technologies of solar cells

A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics –. . A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes. A very thin layer of p-type. . When light photons reach the p-n junctionthrough the thin p-type layer, they supply enough energy to create multiple electron-hole pairs, initiating the conversion process. The. [pdf]
